Filed June 17, 1965, Ser. No. 464,696 Claims. (Cl. 297-186) The present invention relates to an improvement in a combination chair and musical instrument support. More specifically the present invention relates to a combination chair and support for a class or. type of larger horn known generally as a tuba. Briefly the structure comprises an elongated frame having at one end a vertical chairsupport and at the other a corresponding instrument support. The chair is both slidably and rotatably secured to the vertical chair support. A musical instrument gripping device is adjustably secured to its support for establishing the proper attitude of the instrument. Particularly novel are the channel and slotted plate locking means that is foam plastic biased against a slot engaging tongue to give quick adjustment and positive holding of the instrument gripping device in agiven position.

In many musical organizations, such as are found in schools, the musicians are often relatively young and small, lacking in the strength to support a large instrument such as a tuba and thus the need for a support for such an instrument is particularly critical. It is also widely recognized that most damage to an instrument results not when the instrument is being played, but rather when the instrument is set aside or lying around. Thus it is particularly desirable to provide an instrument support to accommodate the different sizes of tubas to avoid these negligent injuries. In these same organizations the instrument is generally owned by the schools and may a be used by several students at different times and thus the instrument support should be readily adjustable to accommodate a plurality of musicians. It is desirable, nevertheless, to allow the instrument to remain in a satisfactorily adjusted position during breaks and the like while allowing a musician to extricate himself without performing complicated gymnastics, from the chair of the combination without disturbing adjustment of the instrument. This is the problem that the prior art has not solved. g

It is an object of the present invention to provide a combination chair and musical instrument support which will accommodate both musicians and tubas of various sizes.

It is a further object of the present invention to provide a combination chair and musical instrument support which will allow the musician to easily extricate himself from the device without disturbing the adjustment of the instrument.

It is still a further object of this invention to provide means for holding adjustments of the musical instrument support once made.

It is yet a still further object of this invention'to provide a chair which is slidably and rotatably secured to the unit so that a musician may easily extricate himself from the combination by sliding backward and pivoting.

It is still yet a further object of this invention to provide a combination chair and tuba support which is comprised of: an elongated frame, adapted to sit firmly on a platform or other flat surface; said frame having, rigidly secured to its rear end, a vertical chair support; a chair which is both slidably, fore and aft, and rotatably, about a vertical axis, secured to said vertical chair support; and a musical instrument support adjustably secured to the forward end of said elongated frame, said musical instrument support being vertically adjustable and pivotable in any direction so as to provide pivotable adjust- 3,259,428 Patented July 5, 1966 ment about a plurality of axes. The actual instrument gripping member is fully adjustable to accommodate a wide range of sizes of instruments with a new and unique locking method comprising: a lipped channel member adapted to slide within a tube member; an elongated slotted plate member transversely movably secured 'to said channel on its inside member and retainer therein by said chanpels lips; resilient means for urging the elongated plate member into engagement with the channels lips; and a locking lip on said tube to engage the slots of the elongated plate member.

Other objects of the invention will become apparent as the description proceeds.

To the accomplishment of the foregoing and related ends, this invention when comprises the features hereinafter fully described and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of the various ways in which the principles of the invention may be employed.

In FIGURES 1 through 12, a frame 21 is adapted to stand firmly on a flat surface by means of suitable legs as at 22 and 23. A vertical chair support 24 is rigidly secured to the rear end of the frame 21. The channel 25 is rigidly secured to the vertical chair support 24 by any suitable means, as for example, by welding. It is desirable to provide chair support brackets 26 as a convenient means for lending greater support to the chanml 25. The chair support brackets 26 are desirably formed of plate stock and are rigidly secured to both the vertical member 24 and the channel 25.

At the forward end of the channel 25 a plate 27 is rigidly secured which acts as a stop to limit the forward sliding motion of the chair 40. The plate 27 may be rigidly fixed to channel 25 by any suitable method as by welding. At the rear end of the channel 25 it is desirable to provide a removable stop to limit the rearward sliding of the chair 40 but which will allow the chair 40 to be removed. One way of accomplishing this is by the use of the angle 28 which is removably secured to the channel 25 by any functional means as by the screw and wing nut assembly 29.

An inverted channel 30 slidably embracing the channel 25 has a web 32 from which the flanges 34 depend and serve to support the lips 31 extending inwardly parallel to the web 32. The channel 30 is wider than the channel v25 so that there is space between the flanges 34 of the channel 30 and the corresponding flanges 33 of the channel 25. The spaces between the flanges 34 and the flanges 33 are, in the preferred configuration, taken up with the resilient angles 35. The resilient angles 35 are desirably rigidly secured to the channel 30 and disposed in such a manner so that one of the legs of each of the angles 35 is disposed in each space between the channel flanges 33 and 34. Angles 35 can be constructed of any firm, resilient material, but are desirably a plastic which has lubricating qualities. One illustrative method of securing the angles 35 to the channel 30 is to thread the cap screws 36 through the angles'35 and channel 30 to the lower bearing plate 37 which is to be rigidly secured to the channel 30. An upper bearing plate 38 is provided and desirably rides on the ball bearings 39 and is rotatably secured to the lowerbearing plate 37. v A chair 40 comprised of a back rest 41 and seat 42 is rigidly secured to the upper bearing plate 39. Thus, it will be seen that a chair 40 is provided which can slide fore and aft and which can be rotated about a vertical axis.

The forward end of the frame 21 is desirably formed of a hollow, vertical standard 50. While the vertical standard 50 may be of any suitable shape, a square or rectangular cross-section has been found to be very practical.

A vertical post51 is provided, with such dimensions as will allow it to be inserted into the vertical standard .50 with a sliding fit so as to provide for a vertical adjustment therebetween. Means are provided for preventing relative motion between the vertical standard 50 and the vertical post 51. One convenient way of doing so is by the locking provision, as is best depicted in FIG- URE 12, wherein a collar 52 is formed with similar dimensions to the vertical standard 50 except that it is not closed. One side of the collar 52 is open with flanges 53 and 54 extending parallel to one another from one .side of the collar 52. It has been found convenient to provide a threaded plate 55 which is rigidly secured to the flange 53 by any suitable means as for example by welding. Threaded into the plate55 is a threaded rod at 56 which is adapted to draw the flanges 53 and 54 together, thus clamping the collar 52 tightly in position. The threaded rod 56 has, rigidly secured at is one end, a handle 57 which is prevented from contacting the collar flange 54 by a washer 58. Threaded rod 56 is inserted through theholes 59 and 60 in the collar flanges 54 and 53, respectively, and threaded into the threaded hole in the plate 55. A retaining ring 61 is permanently aflixed to the end of the threaded shaft 56 to prevent the unit from being lost.

At the upper extremity of the vertical post 51 a horizontal arm 62 is provided. The horizontal arm 62 is dis- I posed rearwardly along the 'axis of the elongated frame 21. 3 A bracket 63 is pivotably secured to the horizontal arm 62 about a horizontal axis transverse to the axis of the .elongated frame 21. The pivoting may be accomplished in any convenient manner as by the use of the nut and ;bolt assembly 64. Plate 65 is rigidly secured between the sides 66 and 67 of the bracket 63. The plate 65 may be so secured by any suitable means which will provide a rigid unit, as for example, by welding. A threaded hole' 68 is provided in th plate 65 and is disposed immediately above the horizontal arm 62. The threaded shaft 69 has a knob 70 rigidly secured to its one end. Threaded shaft 69 is screwed into the threaded hole 68 of the plate 65. The end 71 of the threaded shaft 69 bears upon the upper surface of the horizontal arm 62 thus providing mean-s for making a pivot adjustment about the axis of bolt 64 by screwing in or out the threaded shaft 69.

A spacing block 72 is rigidly secured to th end of the bracket 63 by any suitable means, as by welding. The hole 73 is provided in the spacing block 72.

A universal joint 74 is pivotably secured to the bracket 63. It is desirable to provide a mode of securement which will hold an adjustment once made. Exemplary of such securements is providing a yoke 75 on the universal joint 74 of a larger dimension than the spacing block 72. The resulting gap between the spacing block 72 and the yoke 75 is taken up with friction washers, as for example the fiber washers 76, and a bolt 77 is used as an axis. The bolt 77 is held in place by the nut 78 which is tightened so as to compress the fiber washers 76 thus providing the proper friction joint. It is apparent that the instrument gripping member may be pivoted by manually overriding of the friction in the joint. Unless purposely moved, how ever, the joint will hold its position because of the friction. The universal joint 74 is of a type well-known in the art, adapted to be non-rotating while an instrument is being played. The tubular arm 79 forms a rotatably secured portion of the universal joint 74 and is secured thereto by the bolt 80 which forms the axis of rotation thereof. It is desirable to introduc a friction member into this joint so that an adjustment, once made, will be retained. A suitable friction member is demonstrated by the fiber washers 73 which are interposed between the tube 79 and the yoke 75 of the universal joint 74. The bolt 80 serves as a pivot axis for the tube 79 and is retained by the nut 81 which is tightened so as to compress the fiber washers 73 thus providing the proper friction joint. It is obvious that the instrument gripping means can be pivoted about the axis of the bolt 80 by manually overriding the friction in the joint. Once an adjustment has been completed, however, and the force released, the friction will hold the instrument in position. I

A second tubular structure 82 similar to the tube 79 is rigidly secured thereto at right angles to the tube 79 and extending downward. The tubular structure 82 has, at its lower extremity, a lip 83 at the entry into said tube 82. A built-up male member 84 is of such dimensions as to fit slidably in the tube 82. The built-up male tube is desirably constructed of a channel 84a with lips 85 extending inwardly from the the flanges 86 and parallel to the web 87 of said channel 84a.

A tongue 88 is rigidly secured to the upper end of the male tube member 84. The tongue 88 should be of the largest length dimension which will allow a free sliding fit of the male member into the tube 82. An inspection of FIGURE 3 will make it readily apparent that the male member 84 cannot accidentally drop from the tube 82 since the tongue 88-=will, if the tubes are pulled apart without the locking means being engaged, catch on the lip 83 preventing accidental separation of these items. The male member 84 may, however, be separated from the tube 82 by moving the tube 84 in the direction of the lip 83 thus pivoting the tongue 88 upward allowing it to be slipped out of the tube 82. An elongated plate member 89, of a width greater than the opening between the lips 85 of the channel 84a, is loosely secured to the tongue 88 so that the plate member 89 may be slid over the entire length of the-tongue 88. A convenient meth- -od for accomplishing theaforementioned loose securement of the plate 89 to the tongue 88 is to provide a transverse slot 90 in the plate 89 of such dimensions that will loosely depend from the tongue 88. The plate 89 is disposed within the interior of the channel 84a thus being retained therein by the lips 85. A plurality of regularly spaced slots 91 transverse to the plate 89 are provided therein and are of such dimensions as to allow engagement with the lip 83. It is necessary to resiliently urge the plate 89 against the interior of the lips 85 over the full length of the plate 89. While any type of resilient member that will accomplish the aforementioned end may be used, one very desirable means is illustrated by the use of a resilient plastic foam filling for the cavity or interior of the tube 84.

It will be readily observed that an adjustment may be made, changing the relative positions of the tube 82 to the tube 84, by depressing the plate 89 at its lower end against the urging of the resilient foam filler 92. Such depressing disengages the lip 83.from the slot 91. The tube 84 is then moved either up or down, relative to the tube 82 until it is atthe desired position at which time the plate 89 is released. and is resiliently urged toward engagement with the lips 85. As slot 91 of the plate 89 is placed in engagement with the lip 83, the tubes 82 and 84 are locked to one another.

At its lower end, the channel 84- is desirably bent rearwardly to provide a lower instrument support arm A plate 93 is rigidly secured to the channel 84a between the flanges 86 thereof,'by any suitable means, thus forming a slot 93a. The lower instniment gripping member 94 is comprised of the pads 95 and 96 which are rigidly secured to the bracket 97. Pads 95 and 96 are disposed so as to securely seat andfgrip the base of the instrument intended to be held by said gripping member 94. A tongue member 98 is rigidly secured to the bracket 97. The tongue 98 is desirably of a width dimension which approximates the opening between the lips 85 of the channel 84a. Thus, to insert a lower instrument gripping member 94 one merely places the tongue 98 pointed rearwardly between the lips 85 of the channel 84a and slides the gripping member 94 rearwardly until the tongue 98 is retained by the plate 93 in the slot 93a. The instrument gripping member 94. is locked in place by means of a pin 99. The pin 99 may take the form of a bolt and nut or any other releasable pin. One con venient pin, however, is a sheet metal screw.

Both halves of the tube 79, viz, the portions on each side of the pivotv 80, are identical as are the pieces associated therewith thus only one side will be hereafter described in detail.

A tube 100, of such dimensions as to be readily slidable within the tube 79, is provided. The male-female joint between the tubes 100 and -79 is the same as the vertical joint between the tubes 82 and 84 with-the ex ception that the instant joint is disposed horizontally. The tube 100 is of built-up construction similar to that of the lower support tube 84. The extremity of each of the tubes 79 is formed .as a lip 101 closing off part of the interior of the tube 79. The extremity of the tube 100, which fits into the tube 79, is formed as a tongue 102, of the largest length dimension which will permit a sliding fit with the tube 79. It is thus apparent, fir-om an examination of FIGURE 6, that if the tube 100 is pulled out of thetube 79 to almost its full length that the tongue 102 will interfere and catch on the lip 101 preventing an inadvertent separation of the tubes 79 and 100. It is also apparent that if it is desired to separate the tubes 79 and 100 one merely must move the tube 100 toward the lip 101 which allows'the tongue 1102 to slide free of the lip 101 and the tubes 100 and 79 to be separated.

The tube 100 is desirably formed of a channel 100a with a web 103, flanges 104 and inwardly directed lips 105 depending from the flanges 104 and parallel to the web 103. An elongated plate 106 is loosely secured to the tongues 102 and 79 so that the plate 106 may be moved along the full length of the tongue 102. 'One convenient way of accomplishing the aforementioned loose securement of the plate 106 to the tongue 102 is to provide a transverse slot 107 in the plate 106. The

slot 107 being of such dimensions as will allow free sliding of the plate 106 on the tongue 102. A plurality of regularly spaced transverse slots 108 are provided in the plate 106. The slots 108 are of such dimensions as to be able to engage the lip 101 of the tube 79. Plate 106 is disposed on the interior side of the lips 105 of the tube member '100. Said plate 106 being of .a width dimension which is greater than the distance between the lips 105. Thus, it is apparent that the lips 105 will retain the plate 106 Within the interior of the tube 100. Resilient means are provided to urge the plate 106, uniformly along its full length, against the lip 105 of the channel a. Said resilient means may be of any suitable type which will accomplish this end, but a very desirable and convenient means is provided by cfilling the interior of the tube with a resilient plastic foam 109.

It is obvious that to extend or decrease the length of the instrument support arms the plate 106 is depressed at its exposed end. Slot 108 is thus freed from engagement with the lip 101 leaving the tubes 100 and 79 in an unlocked relation. The tube 100 is then either slid into or is withdrawn from the tube 79 to the desired position. The resilient material 109 will resiliently urge the plate back to a position against the lips when the pressure on the plate 106 is released. A slot 108, when engaged by the lip 101, will lock the tubes 79 and 100 in rigid relative relation to one another.

The tube i100 has, at its opposite end and rearwardly disposed, .an instrument support arm. A plate 110 is rigidly secured between the flanges 104 of the channel 100a the instrument support arm by any suitable means as for example by welding thus forming the slot'111. The musical instrument gripping member 112 is comprised of pads 113 and 114 which are rigidly secured to the bracket 115. A tongue member 116 is'rigidly secured to the bracket 11 5. Said tongue member 116 is of such a thickness so as to form a iirm sliding tit between the web 103 and the plate 110 in the slot 111 .and of a width which just allows it to pass through the opening between the lips 103 of the channel 1004. The instrument gripping member 1 12 is retained in position by providing a pin 117 to prevent sliding of the tongue 116 out of the slot 111. The pin 117 may take the form of a nut and bolt or any other readily movable pin type fastener. One very convenient pin 117, however, is a sheet metal screw.

It will be noted that it is very convenient, from a manufacturing point of view, to provide that the male members 84 and 100 are interchangeable. Thus, in any unit sold, three members 84 will be provided keeping a replacement inventory to a and preventing possible confusion and mixing of non-interchangeable parts in the packing of the original unit.

It will be noted that three dimensional pivotable adjustments of the instruments are available via pivoting universal joints. A vertical adjustment is accomplished by raising or lowering the vertical post 50 within the vertical standard .51 and locking it in position with the collar 52 and clamping mechanism provided thereon. The instrument once clamped into the instrument support may be tilted to and from the musician by turning a knob 71 one way or the other. T1116 instrument'may be given a' yaw adjustment by pivoting the instrument about the bolt 77, as is desired; the adjustment being held by the friction member 76 in this joint. A list, or sideway tilt to either side may be accomplished by pivoting the instrument support about the bolt '80, the adjustment, once made, is held by the fiber friction Washers 73. The instrument gripping members 94 and 112 having been adjusted so as to firmly clamp and hold the tuba to be used. It is thus obvious that a new and very useful combination chair and tuba support which is fully adjustable to accommodate tubas and musicians of various sizes is herein described.
